+= Open Simulation Interface (OSI) C++ Bindings
+
+This section explains how to integrate OSI into your own C++ project.
+The C++ bindings are available in the separate https://github.com/OpenSimulationInterface/osi-cpp.git[osi-cpp] repository.
+
+You can refer to an example application in the examples of the
+https://github.com/OpenSimulationInterface/osi-sensor-model-packaging/tree/master/examples[OSI Sensor Model Packaging] repository.
 
 == Prerequisites
+- cmake (version 3.10.2 or higher)
+- git
+
+== Checkout the repository with submodules
+
+. Open a terminal in your project.
+. Clone the osi-cpp repository, including sub-modules:
++
+----
+git clone --recurse-submodules https://github.com/OpenSimulationInterface/osi-cpp.git
+----
+
+
+== Using vcpkg for dependencies (Recommended)
+
+Especially for building on Windows, the use of **vcpkg** to handle dependencies is recommended.
+
+Prerequisites::
+* The environment variable `VCPKG_ROOT` must be set to the root of your vcpkg installation.
+* For Windows static linking, the static-md triplet is recommended (see also <<static_dynamic_linking, Static/Dynamic Linking>> explained below)
+
+Steps::
+. Configure the build using the vcpkg preset:
++
+----
+cmake --preset default
+----
+. Perform the build:
++
+----
+cmake --build build
+----
+
+
+== Building without vcpkg
+
+To build without vcpkg, you must ensure necessary prerequisites are installed and detectable by CMake. It is then usually enough to include the `osi-cpp` repository in your main `CMakeLists.txt`:
+----
+set(LINK_WITH_SHARED_OSI OFF) # Check linking explaination below
+add_subdirectory(lib/osi-cpp) 
+target_link_libraries(YourTarget open_simulation_interface_pic)
+
+----
 
-* You have installed _cmake_ (version 3.10.2 or higher)
-* You must have superuser privileges
+== Static/Dynamic Linking [[static_dynamic_linking]]
 
-Static linking is the recommended way to package OSI FMUs for sharing with others to be integrated in a co-simulation: They should have minimal external dependencies in order to ensure maximum portability.
-For other use cases like first trials to get started with OSI, dynamic linking could be an option as well.
